Abstract:LiCoO2 with Layer structure has been used as a cathode material in lithium batteries. Recently, it is found that the nanostructured LiCoO2 powders exhibit an enhanced electrochemical performance compared to their bulk. Physiochemical properties of the nanocrystalline LiCoO2 powders like crystallite size, homogeneity, chemical stability etc., are mainly depending on the synthesis process. A number of wet chemical routes were investigated for the synthesis of nanocrystalline metal oxides including LiCoO2 powders. Among them, polymeric precursor route is found to be a simple and effective soft combustion process for the synthesis of nanocrystalline multi-component oxide powders relatively at lower temperatures. Hence, in the present work, nanocrystalline layered LiCoO2 powders were prepared by polymeric precursor route using citric acid and glycerol as polymerizing and chelating agents. The complete process was investigated through XRD, FTIR, TG/DTA and SEM techniques. The crystallite size calculated using XRD data is found to be 45nm. SEM image of LiCoO2 powder exhibit an agglomeration of fine LiCoO2 particles.
